There have been differences in the naming and writing of tricks. Notably, differences in the placement of trick rotation direction and the # of spins during a trick.

To further ease the process of writing and reading trick names, the Naming Committee has standardized the process as follows:

(Modifier) (Trick Name) (Direction) (number of spins) (starting position)-(ending position)

Example:
Inverse Shadow Normal 2.0 23-12

Eh... No. According to the recently released article by the Naming Committee regarding the Sonic/Shadow definitions, the Sonic is restricted to only one rotation. So the notation for the number of spin does not apply for the Sonic.

Which is why it says Shadow, not Sonic.

If I were to notate Inverse Sonic from the same fingers, it would have to be:
Inverse Sonic Normal 1.0 23-21

Hmm... There is actually a more detailed "naming conventions" done by Phya in the vault.
I'll not be copy-pasting the whole post here, since it's supposed to be in the vault anyway. Though some of it may be a little outdated, it's a good material to refer from.
Get somebody that can access the vault to post it in the NC forum. ;)

Edit: ^ heheh. It was Sonic before you edited it. No? B)

Nope, it still says Shadow in the text that yxTay quoted.

I'm just assuming that he quickly looked at it and thought it said Sonic. I had to re-read the post a few times to make sure it actually did say Shadow. :lol:

So now, the Reverse modifier is before the trick name... Darn, I just got used to doing it after the trick name too. :(

Well, thanks for announcing it, anyways. Let's hope everyone makes use of it.

Wouldn't "reverse" come under direction instead of modifier?

Huh? Isn't the direction of spin still after the trick name?

Eh... Okay. I guess I had mistaken it. *opps*

As mentioned by adam25, the Normal/Reverse is a notation for the direction, so it comes after the trick name.

What about tricks like fake reverse? That trick doesn't have normal variation

Fake reverse isn't exactly an official name. When (hopefully not if) we work out a notation for spin transfers, this would be a trick that gets a different name.

...Oops. I should have observed it better. Silly me.

Under current definitions, the Fake Reverse is the same as Tap Reverse 1.0, i.e. Full Tap Reverse. Therefore, the trick do have a normal variation.

In any case, the naming convention here is only a general one. It doesn't apply in the same manner to every trick, just most of them. There will certainly be exceptions.
